Digital Watermarking and Steganography: Fundamentals and Techniques, Second Edition

This book intends to provide a comprehensive overview on different aspects of mechanisms and techniques for information security. It is written for students, researchers, and professionals studying in the field of multimedia security and steganography. Multimedia security and steganography is especially relevant due to the global scale of digital multimedia and the rapid growth of the Internet. Digital watermarking technology can be used to guarantee authenticity and can be applied as proof that the content has not been altered since insertion. Updated techniques and advances in watermarking are explored in this new edition. The combinational spatial and frequency domains watermarking technique provides a new concept of enlarging the embedding capacity of watermarks. The genetic algorithm (GA) based watermarking technique solves the rounding error problem and provide an efficient embedding approach. Each chapter provides the reader with a fundamental, theoretical framework, while developing the extensive advanced techniques and considering the essential principles of the digital watermarking and steganographic systems. Several robust algorithms that are presented throughout illustrate the framework and provide assistance and tools in understanding and implementing the fundamental principles.

本書旨在提供有關資訊安全機制和技術的綜合概述。它針對在多媒體安全和隱寫術領域學習的學生、研究人員和專業人士撰寫。由於數字多媒體的全球規模和互聯網的快速增長，多媒體安全和隱寫術尤其重要。數字浮水印技術可用於保證真實性，並可作為證明內容自插入以來未被修改的證據。本新版探討了浮水印技術的更新技術和進展。結合空間和頻率域浮水印技術提供了一種擴大浮水印嵌入容量的新概念。基於遺傳算法（GA）的浮水印技術解決了四捨五入誤差問題，並提供了一種高效的嵌入方法。每一章節都提供了讀者基礎的理論框架，同時發展了廣泛的高級技術，並考慮了數字浮水印和隱寫系統的基本原則。全書介紹了多個強健的演算法，以說明框架並提供幫助和工具，以理解和實施基本原則。
